The Omicron variant of the coronavirus is spreading quickly in the United States. Reported covid-19 circumstances are sharply rising in extremely immunized cities like New York, and consultants count on the variant to develop into the dominant type of the virus seen within the U.S. in as little as a couple of weeks, following the sample seen in different international locations. Here’s what is thought thus far, based mostly on preliminary stories—as extra analysis is carried out, our understanding of this variant is will evolve.

What Are the Most Common Omicron Symptoms?

Early information from South Africa, the place the variant was first found in late November (however not essentially the place it originated), and different international locations is beginning to paint a clearer image of the difficulty Omicron may cause. It’s infecting individuals who have a baseline of immunity, both from earlier vaccination or an infection, however its typical signs additionally seem, a minimum of thus far, to be milder on common. A case examine of an Omicron-specific outbreak amongst individuals in Norway—the overwhelming majority of whom had been totally vaccinated—found, as an illustration, that early signs predominantly included sore throat and a runny or stuffy nostril, together with dry cough and fatigue. Interestingly sufficient, that very same examine discovered that solely 12% reported a lack of scent, which was beforehand recognized to be a quite common symptom of covid-19. In South Africa, fewer hospitalizations and deaths have been associated with their latest Omicron wave than with previous peaks, together with from Delta.

There is lab information suggesting that Omicron can develop very quickly within the cells of our higher respiratory tract however not as nicely in our lungs. This may assist clarify why Omicron is so fast-spreading and why it doesn’t appear to trigger as a lot severe sickness. However, it’s too early to know whether or not Omicron is inherently milder than older strains of the virus. Because a lot of the world has been uncovered to some model of the coronavirus, both via an infection or vaccination, the milder presentation we’re seeing thus far could not maintain true for unexposed individuals.

Omicron does nonetheless pose a serious risk, consultants have warned. Though the typical particular person could also be advantageous after contracting Omicron, its sheer unfold will result in many individuals getting sick without delay, which might pressure native healthcare techniques. At least a few of these individuals gained’t fare in addition to everybody else, particularly in the event that they’re in poorer well being and/or not beforehand uncovered. At this level, we additionally don’t know the probability of individuals experiencing persistent signs after Omicron, a situation often known as lengthy covid. Even if solely a small share of individuals do develop lingering signs, that would nonetheless quantity to many circumstances in whole.

When Should You Get Tested?

If you’ve been round somebody who had covid-19, you could be questioning how quickly you will get examined to seek out out should you caught the virus. The excellent news is that Omicron isn’t so inherently completely different from previous variants that checks aren’t choosing it up. But there’s some information from South Africa suggesting that signs can seem sooner following publicity—also called the incubation interval—in comparison with earlier strains. Omicron signs might be displaying up after three to 4 days on common, in comparison with the typical five-day incubation interval seen earlier than. So that could be the time to get examined with PCR should you’re afraid you’ve been uncovered to Omicron.

Even should you check unfavorable quickly after publicity to an contaminated particular person, subsequent checks should still be prudent, since some infections could solely develop into detectable per week or extra after publicity. Rapid checks nonetheless appear to be efficient at detecting when an individual is most infectious and capable of unfold the virus to others, however there’s some hypothesis that speedy checks could not identify infection as shortly as earlier than. So in case you are counting on these checks, it could be extra necessary than ever to take the check instantly earlier than you propose to go to somebody, not a day or many hours earlier. And should you’re feeling sick, you must attempt to keep dwelling regardless, if potential.

How Effective Are the Vaccines and Boosters Against Omicron?

It’s clear by now that our vaccines aren’t offering as a lot safety in opposition to an infection from Omicron as previous strains. But that doesn’t imply they’re not serving to. Multiple research have proven that booster photographs do appear to considerably restore effectiveness in opposition to Omicron, a minimum of briefly.

New information from vaccine maker Moderna out Monday, as an illustration, checked out individuals’s neutralizing antibody ranges in opposition to Omicron earlier than and a month after they obtained a booster dose. Some got the usual 50-microgram booster dose (half of the total dose used within the two-series vaccine), whereas others got a 100-microgram dose. Compared to pre-booster ranges, ranges rose 37-fold in those that obtained the usual booster dose, with an 83-fold for individuals who obtained the 100-microgram booster.

There are caveats right here. The experiments used pseudovirus meant to seem like Omicron, which will not be an actual match for a way our boosted immunity will reply to the actual factor. That stated, some early real-world information from the UK has indicated {that a} booster could restore safety in opposition to sickness from Omicron to round 70% to 75%, with even higher safety in opposition to extreme sickness.

Companies like Moderna are growing Omicron-specific boosters, however they could not arrive for a while, and who is aware of what the scenario may seem like then (previously, variant-specific boosters had been outdated earlier than they might conceivably attain the market, supplanted by newer strains that grew to become dominant). So within the speedy future, getting boosted might be probably the most impactful factor you are able to do for your self to remain secure this winter.
